为了有效地检测鸡资源群体中的数量性状基因座（QTL），必须建立一张详细的连锁图谱。在这项研究中，微卫星标记分离（CA）（n）-丰富的图书馆（指定为ABR标记）使用的日本游戏和白色来航鸡之间的杂交发展的群体进行定位。共获得296个标记，其中ABR标记193个，MCW标记43个，ADL标记31个，LEI标记22个，HUJ标记3个，GCT标记2个，UMA标记1个，ROS标记1个。此外，基于鸡草图基因组序列将5个标记分配到图谱上，使图谱上的标记总数达到301个。该连锁图谱的构建将有助于鸡QTL定位。
A detailed linkage map is necessary for efficient detection of quantitative trait loci (QTL) in chicken resource populations. In this study, microsatellite markers isolated from a (CA)(n)-enriched library (designated as ABR Markers) were mapped using a population developed from a cross between Japanese Game and White Leghorn chickens. In total, 296 markers including 193 ABR, 43 MCW, 31 ADL, 22 LEI, 3 HUJ, 2 GCT, 1 UMA and 1 ROS were mapped by linkage to chicken chromosomes 1-14, 1.7-21, 23, 24, 26-28 and Z. In addition, five markers were assigned to the map based on the chicken draft genomic sequence, bringing the total number of markers on the map to 301. The resulting linkage map will contribute to QTL mapping in chicken.
